UNITED STATES PATENT OFFCEt ISAAC ELLIS AND MELVIN I. ELLIS, OF NORWOOD,MASSACHUSETTS.

PROCESS OF COLORlNG, EMBELLISHING, AND DISCHARGING COLOR IN THEMANUFACTURE OF PAPER.

SPECIFICATION ferming part of Letters Patent No. 330215, dated November10, 1885.

Application filed July 31, 1885. Serial No. 173.193. (No model.)

TO all whom it may concern:

Be it known that we, ISAAC ELLIs and MELVIN I. ELLIs, citizens of theUnited States, residing at Norwood, in the county of Norfolk and Stateof Massachusetts, have invented a new and Improved Process of Coloring,Embellishing, and Discharging Color in the Manufacture of Paper, ofwhich the following is a Specification.

The object of our invention is to print or color in various designs uponpaper in the process of manufacture, or, if desired, where colored paperis being made, to remove a portion of the color in the same so as toleave a design in white upon said paper.

In Carrying out our invention we employ a roller with the desired designengraved in relief on its periphery and running in a tank to Which coloror any suitable Chemical is supplied from a reservoir, the coloredsubstance being kept at the proper height in the tank by any suitablemeans, and the said tank and roller being placed in any desired positionbetween the coucher 77 and the calender-rollers on the paper-makingmachine.

Referring to the accompanying drawings, Figure 1 represents a portion ofa papermaking machine embodying our inveution. Fig. 2 is a Verticallongitudinal section through the feeding-tank and reservoir, showing theprinting-roller and other parts in elevation'. Fig. 3 is a Verticalcross-section taken on line a; x of Fig. 2. Fig. 4 rcpresents a piece ofpaper as it would be if printed with a roller engraved with a designlike that shown in Figs. 2 and 3.

A represents the frame of a paper-making machine; B, thecouching-roller; C C, presses; D D, driers, and E the calendering-rolls.In any suitable position between the coucher and the calender -rolls,but preferably between the presses and driers, we place a coloring orprinting roll, F, mounted in suitable standards or bearings, G, so as tobe free to rotate in a tank, H, that is supplied with any desirablecoloring-matter from a reservoir, I, the said coloring-matter being keptat a proper level in the tank H by means of a ball-cock, K, or othersuitable device. The tank His fitted With an overflow, L, in case theball-cock H should at any time get out of order.

The printing-roll F is engraved with any desired design and caused torotate by the pressure of the paper as it passes from the guide-rollerM, in front of the presses, to the guide-roller M', at the rear of thedriers, the height of the liquid in the tank H belng such that only theprojecting' portions of the roller will dip into it, which, being thuscovered with coloring-matter, transfer it to the paper passing over theroller.

When colored paper is being manufactured, and it is desired to have adesign formed thereon by discharging the color, a suitable Chemicalpreparation is placed in the tank, instead of a colored solution which,being brought into contact with the paper by the design on the roller F,will cause the color to be discharged therefrom, and thus form thedesign upon the paper as it passes over the roller.

When very thick coloringmatter is employed such as printing-ink-it maybe found advantageous to employ a small roller over the center of theroller F to press the' paper onto the same, such roller not being shownin the drawings, as it will not be required when printing with ordinarycolor.

If desired to have a design with more than one color, two or morerollers F may be employed, each running in a tank containlng differentcolor.

What We claim as our invention is 1. The herein-described process ofimparting a design to paper after it passes from the coucher and beforeit arrives at the calenderrolls in the process of manufacturc,Substantially as described.

2. In a paper-making machine, the roller F, engraved With any desireddesign and running in a tank, H, in which coloring flnid is kept at aproper level, the same being placed between the coucher andcalendenrolls, substantially as shown and described.

3. The combination of the roller F, tank H, reservoir I, supply-pipe J,and a ballcock, K, in a paper-making machine, for imparting designs tothe paper as it passes from the coucher B to the calender-rolls E in theprocess of manufacture, substantially as described and shown.

In testimony whereof we have signed our IOO names to this Specificationin the presence of 5 E. PLANTA.
